VICTOR GARLSON, OF CHATCOLET, IDAHO LIQUID-FEED GOVERNOR.

' Application fiieamne 1,1915. Serial No. 31,435.

To all whom it may concern Be it known that I, VICTOR citizen of the United States, residing at Chatcolet, in the county of Kootenai and State of Idaho, have invented certain new and useful Improvements in Liquid-Feed Governors, of which the following is a speci fication. 1 I

This invention relates to improvements'in liquid feeding governors, especially adapted for liquid separating mechanism of the centrifugal type.

The invention relates more particularly to that class of governing feeding devices including a valve, controlling the flow to the separator, the valve beingopened only after the separator has attained a predetermined speed. In this class of feeding devices it is important that the controlling valve operates instantly toward a closing position when the speed decreases from a predetermined standard and therefore it is one of the ob jects of this invention to provide a spring controlled valve, the spring acting normally to close the valve against the action of the governor to open the same. By means of this combination, the controlling valve is never opened until the governor positively actuates the same upon the attainment of said predetermined speed, and further, reli ance is not placed upon the governor to close the valve when the speed lowers.

My invention alsoincludes an improved speed indicator which may be adjustably connected for operation by the governor.

In order to enhance the sensitiveness of the device to sudden changes, due to varying speed, it is important to have a quick opening and closing movement of the controlling valve, therefore I have provided an im proved closure having ingress and egress ports, preferably'arranged to provide for equal liquid passage area,

ports and arranged in such a manner that will be enough to close or open the. ingress ports thereby alwavs leaving the egress port open even when the valve is in a closed position.

My invention has many other objects and features which will be more fully described in connectionwith the accompanying draw Specification of Letters Patent.

Fig. 2, is a View in side elevation, with parts in section, showing my improved governor device. Fig. 3, is a detail view of the portion of the bracket on which m' device mounted. Fig. 4., is a sectional view on line 4-4 of Fig. 2. Fig. 5, is a view looking from the left of Fig. 2, indicator in elevation and also showing the link connection between the controlling shaft and the controlling valve. in perspective of a portion ing of the separator and showing the disposition of the controlling valve in the supply pipe. Fig. 7, is a sectional view on line 77 of Fig. '8. Fig. 8, is a sectional view on line 8 -8 of Fig. 7. Fig. 9 is a sectional view on line 99 of Fig. 8.

Like characters of reference designate similar parts throughout the different figures of the drawings.

As illustrated, 1 designates a frame of the separator on which is mounted the bowl casing 2 having liquid discharge spouts 3 and i for the discharge of separated liquid.

A supply tank is indicated at 5 and communicates with the supply pipe 6 which delivers the liquid to be separated into the bowl. A controlling valve is indicated at 7 and is showr'f'more particularly in Figs. 6, 7 and 8, to which reference will now be made. Said valve includes a valve casing 8, interposed in the pipe 6 near the discharge end of the latter. The casing 8 is provided with a rectangular ingress port which is preferably divided into two ports 9. Said casing is provided with an egress port 10 which comprises a single undivided opening of a liquid volume passage capacity equal to or substantially equal to the passage area of the ports 9. A rotary valve closure 11 is casing and is provided with a cavity 12. The cavity 12 is provided with divided ingress ports 13, ada ted to register with ingress ports 9, as s own in Fig. 7. Said va is also provided ,with a single egress port 14, adapted to registenwithegress port 10,

While I have shown this featurecmbodied in a rotary valve,

feature of the invention is limited to an em- 20 bodirnent of this i I do not consider that this particular type of valve. It isa-n important matter intthis class of 7 {devices to have allofthc parts readily rcmovable so that they n ay belmaintained inn clean .and sanitary condition and I have pro advantageous structure whereby the closurell may be readily removed from sce ns' In the embodiment shown, the valve, casing is'prov'ided with a flange 15 from which so oppositely disposed hook shaped pins 16 project. A. closure disk 17 is providedwith adapted for projection hook ei'uls will engage thesurface of'the disk 85 and hold the lotto! in the Josition shown-in Fig.3. liiounted upon the closuredisk 1.7 is' a journal bracket 19, of generally U- shaped construction, one limb 20 thereofv being mounted upon the disk 1-? and the other 10 limb 21 thereof being disposed in spaced relation with rc'spectto said disk. The clos u're 11 isprovid'ed with a closure 'stenr22 w-hich is journaled in the closure disk 17 and also in the limbs 20 and 21 of the An operating arm 23 is fixed on the spindle for connection with apparatus 'n'esently to be described, and coil spring 24 is wound about the spindle 22 between the limb 21 thereof and said arm 5o 2.3! llnc iend of-the coil springfl i, as indicated at 25, engages the bracket 19 andthe otllcr'end 26, engages the 21 111.23 andurges :thelatterina direction to'close the valve.

Said bracket 27 is provided with a horizontal portion 30.having a depending journal 31. The bracket is oifset at 3'2 to provide a journal bearing for shafts aboutito be described, and said bracket has a horizontal extension 33 in which is journaled a vertical disposedgoi The improved governo'rfid cludes a sleeve ondin a bearing 35, formed in an extension of'part 33. Shoulders36 and 37 areformed onthe sleeve 34- so. that the letter will be held against longitudinal movement. A bevel gear 38 is mounted on or formed with the sleeve 34 and meshes with a bevel car 39 mounted upon shaft .40. Shaft .40 1s journaled in bearings 3l 'and 32' and carries a by a gear wheel 42, operated by the usual crank 43. A 1on gitudinally niovable governor spindle 44 is ment therein as well as longitudinal move n' ent. On the upperendof said spindle is mounted a governorbar 45 to whlch gover- 3% which is journaled in 33,

Anexpnnsively acting spring 49 is interposed between the sleeve 3%- and the governor ball 45 so as norni ally to lift the latter and force the governor balls into the position shown in Fig. 2.

It will now be seen thatcentrifugal spreading movement of the governor arms will be resisted by the spring 49 andthe spring 57.

On the outer end of the controlling shaft 54 is mounted an arm 60 to which ispivoted one end of a link 61, as indicated at 62. The link ma be jointed, as indicated at 63, if de sired. he remaining end of the link 61 is releasably connected, as at 64, with arm 23, and ma be jointed, as indicated at 65 Now be seen that contra-clockwise adjustment of shaft 54 will serve to open the controllin valve and that a clockwise movement shaft would tend to close the controlling valve. However, as before stated, reliance is not placed upon transmission of power from the governor to the controlling valve to close the latter, as the latter'w-ill be instantly closed by its spring 24 as soon as {stress on the arm 23 has been released;

A bracket 66 extends upwardly from bracket 27 and terminates in a graduated scale 67. A s indle68 is mounted in said bracket 66 an carries an index 69' adapted 'to traverse the graduated'scale. An arm 70, mounted on said s indle 68, isconnected at 71 lie remaining end of link 7 2 adjusting nut 74 may include opipositely disposed nuts 75 which may be a justed on a v threaded arm 76, mounted on shaft 54, to

ve an accurate speed reading of the device.

hus the operator will merely have to glance at the speed indicator to know whether or not he is operating the machine at the required speed which is necessary to give the maximum separating efiiciency and the inlet to the bowl is automatically controlled so that no li uid will be permitted to enter the bowl unti a predetermined speed has been attained.

It is believed that the advantages and utility of my invention will be clearly underv stood from the foregoing description, and while I have herein shown and described one specific form of my invention, I do not closure in said casing provided with a stem,
